WATER-CLOSET.

SPECIFICATION formingpart of Letters Patent No. 243,719, dated. July 5, 1881.

' I Application filed AprillS, 188i. ModeL) To all whom it'may concern:

- Be it known that I, ANDREW G. MYERS, of New YOI'ILGitYfCOHIltY and State of New York, have invented certain new and useful Improvements in Water-Closets, of V which the following is a specification.

My invention relates to that class of closets in which the basin is provided with a hollow flushing-rim at the top to discharge a scour'- ing stream or sheet of water downward around the sides of the basin, and also to such closets as have an upright limb or chamber adjacent to the basin which contains the valve that controls the discharge from the basin to the underlying trap.

- My improvement aims to produce a more effective scouring-wash from the flushing-rim, and also to provide the upright limb with a similar scouring-wash down and around its sides and upon the inclosed valve whenever the closet is operated.

My improvement also partly consistsin the construction of the seat relatively to the basin, as hereinafter set forth.

Figure l of the drawings annexed presents a side elevation of a well-known form of water-closet embodying my improvements, and represented as broken away at certain parts to better illustrate the same. Fig. '2 is a plan view of Fig. 1, also partly broken, with the same object.

In these figures only the basin and valvechamber or upright limb is represented, the trap onto which these are set not being shown.

The basin a has a wide inclined neck, I), at its base, which opens into the upright limb or valve-chamber 0, above a contraction or shoulder, 01, therein, while the contracted neck 6 at the base of the valve-chamber connects with the trap or offset in the usual manner of closets of this kind.

The discharge valve or plunger, which is inclosed in the limb 0, but is not shown, seats on the shoulder d, and thus closes communication with the trap, so as to retain the body of water which enters the closet to the regular depth, and when the valve is raised this water is allowed to suddenly descend into the trap, and thus cleanse the closet in the usual way.

The water-pipe connects to the nozzle f, which extends tangentially from the rim of the basin, and opens inwardly into the hollow flushing-rim g, which runs around the interior of the basinin about the usual manner, as illustrated. When thedischarge-valveis raised the water-valve is simultaneously opened and a stream of water enters the flushing-rim tangentially through the nozzle f, and thence sweeps centrifugally around the same and escapesiu an annular sheet down and around the sides of the basin, so as t to cleanse and flush the same in the usual manner, as will be understood. It is desirable, however, that this stream or sheet should issue from the rim against the sides of the basin with the greatest possible energy, surge, or agitation, so as to produce an energetic scouring action therein, to effectually remove all adhering deposits and render the basin thoroughly clean at each action. Heretofore this has not been effected to a desirable extent, for the flushing-rims have been constructed with a uniform or smooth interior, which allows the w ater to escape into the basin in a too smooth and uninterrupted manner.

Now, according to my improyement, I construct the interior of the flushing-rim so as to present a number of'projections, h h, to the passage of the centrifugal stream which sweeps around the rim, so thatthis stream becomes partly intercepted or broken up at several points, and strong jets are directed or deflected therefrom vdownward at various points around the basin, so that the stream issuing from the rim becomes interrupted at various points around the basin, and variable in force and volume, in such a way as to produce a very energetic agitation or surging stream down and around the sides of thebasin,which produces an effective scouring action therein that is very much desired. These projections h h preferably extend in two opposing series, as shown, one series from the side of the basin directed inward, and the other series from the flushingrim directed outward, as seen in Fig. 1; and as shown in Fig. 2 the projections in the two series preferably alternate with each other around the rim. It will be understood, however, that these projections may be arranged or constructed in various other ways without departing from the principle described.

N ow, another feature of my invention consists in means for causing a scouring-wash down the sides of the upright limb or valvechamber and against the inclosed valve or plunger simultaneously with the wash in the basin. This I effect by forming the limb c with an encircling or partly-encircling waterchannel, '5, around its upper part, which opens through the walls of the limb by'a'number of perforations in regular or irregular order around the same, as seen in Figs'l and 2, and I extend a water-duct, 7c, therefrom to the water inlet or nozzle f of the basin, so that when the water is discharged into the basin a simultaneous discharge occurs in the limb or valve-chamber c, partly in the form of an annular surging or scouring stream down around the sides of the chamber, and partly in jets across the chamber, which strike the inclosed plunger or valve and run down the same, thus effectively washing these parts and preventing the lodgment or adhesion of ofl'ensive deposits, or removing such as may at any time momentarily adhere, thus keeping the closet in a clean healthful condition. Heretofore little or no wash has been provided in these parts of this class of closets, which is, in fact, very much required, as these parts are particularly liable to accumulations which cannot be reached or removed, as would be the casein the basin; but the means described of energetical] y washing said parts at each action of the closet effectually obviates this objection and forms a material improvement in closets of this class.

The entire closet, as shown in the drawings, with its water-ducts and flushing-rims on basin and valvechamber, is preferably made in one continuous structure of earthenware, whereby all joints and breaks are obviated; but I do not, of course, limit myself to this material.

The remaining feature of my invention 'relates to the seat.

In many cases it is desirable to have the seat fixed directly to the basin and of a size just sufficient to encircle the same, and thus dispense with a riser and inclosing-case, ordinarily used to support the seat and inclose the closet. This is desirable for hospitals and public places where it is usually preferable to have the closet exposed, so that the attendant may always know its condition, and also afford as little chance as possible for the accumulation or concealment of infectious or offensive matter. For hospital purposes such seats are usually made of earthenware or glazed iron, in the form of a narrow oval rim to just fit over the rim of the basin, and to lift on or off, as required but these are unpleasant to the body, on account of their coldness, and are injurious to some patients. Besides, if in case of infection their destruction should become necessary, their expense would be appreciable. N ow, in mycase, I construct the seat of wood, as shown at l in Figs. 1 and 2, in the form of a ring of oval or other suitable shape, which rests directly upon the rim of the basin, and is secured thereto by screws m, screwed into leaden or similar plugs, n, which are run into dovetailed cavities in the rim, as fully illustrated in Fig. 1. The wood, being a non-conductor, is pleasant to the body, and its material and construction being cheap, an infected lid'maybe readily destroyed by burningand a new one substituted with comparatively little expense. Besides, thelid, when af-. fixed, is secure against displacement, yet by means of the simple fasteningsshown may be readily removed and refixed, as occasion may require.

What I claim is- 1. In a water-closet, a flushing-rim provided with projections on its interior, substantially as and for the purpose herein set forth.

2. A water-closet of substantially the kind described, having an upright limb or valvechamber adjoining the basin, with a waterchannel formed in or on its Walls, encircling- 3. A water-closet of substantially the kind described, formed with a basin, a, and upright limb or valve-chamber c adjoining the same, and provided with a water-nozzle, f, connecting to said basin, and a water duct and channel, is i, leading therefrom and extending about and discharging interiorly therein and around the sides of said limb, the said parts being formed in one continuous structure of earthenware, substantially as and for the purpose here in set forth.

4. The combination of a water-closet basin having a rim formed to directly support the seat, and provided with attaching-plugs n let into the rim, with the seat I, supported'on said rim, and screws m, extending through the same into the said plugs, substantially as here in shown and described.
